Jonathan Klein knows the power of a photograph. As the head of Getty Images, he oversees a collection of approximately 70 millions photos (photos which MPR and other news outlets draw from on a regular basis).
In this short but pointed presentation, Klein takes us through some of the most iconic images from the last century, and how they changed the world.
Note: You may find some of these images disturbing to look at. Most are on the screen for only a few seconds.
